ComfyUI Node: Gemini Prompt Expander 🪄

Gemini Prompt Expander 🪄:

The GeminiPromptExpander is a powerful tool designed to enhance and expand textual prompts for AI-generated visual content. Its primary function is to take a simple input prompt and transform it into a detailed, structured format that can be easily interpreted by AI models to produce visually compelling results. By breaking down the input into specific categories such as type, subject, outfit, pose, scene, and technical details, the node ensures that the AI has a comprehensive understanding of the desired output. This structured approach not only aids in achieving more accurate and visually appealing results but also streamlines the creative process for AI artists by providing a clear and concise framework for prompt expansion.

Gemini Prompt Expander 🪄 Input Parameters:

input_text

The input_text parameter is a required string input that serves as the initial prompt you wish to expand. This is the core content that the node will process and transform into a more detailed and structured format. The input should be a concise description of the visual concept you want to generate, and it is crucial for setting the direction of the expansion process. There are no specific minimum or maximum values, but it is recommended to keep the input clear and focused to ensure the best results.

api_key

The api_key is an optional string parameter that allows you to provide an API key for authentication purposes. This key is necessary if you want to utilize external services or models that require authentication. If not provided, the node will attempt to retrieve the API key from the system environment variables. The default value is an empty string, and it is important to ensure that a valid API key is available to avoid execution errors.

unique_id

The unique_id is a hidden parameter used internally to identify the specific node instance within a workflow. It is not intended for manual input and is automatically managed by the system to ensure the correct association of expanded prompts with their respective nodes.

extra_pnginfo

The extra_pnginfo is another hidden parameter that stores additional metadata related to the prompt expansion process. It is typically used to pass workflow-related information and is not meant for direct user interaction. This parameter helps maintain the integrity and context of the expanded prompt within the broader workflow.

Gemini Prompt Expander 🪄 Output Parameters:

STRING

The output of the GeminiPromptExpander is a single string that represents the expanded prompt. This output is a detailed and structured version of the input text, formatted into specific categories such as type, subject, outfit, pose, scene, and technical details. The expanded prompt is designed to provide AI models with a comprehensive understanding of the desired visual output, ensuring more accurate and visually appealing results. This output is crucial for AI artists who wish to generate high-quality visual content based on their initial ideas.

Gemini Prompt Expander 🪄 Usage Tips:

• Ensure that your input_text is clear and focused to achieve the best expansion results. A well-defined prompt will lead to a more accurate and visually appealing output.
• If you encounter issues with authentication, double-check that your api_key is correctly set either as an input parameter or as a system environment variable.
• Utilize the expanded prompt's structured format to guide AI models in generating content that closely matches your creative vision.

Gemini Prompt Expander 🪄 Common Errors and Solutions:

No API key provided. Please enter an API key or set the GEMINI_API_KEY environment variable.

• Explanation: This error occurs when the node is unable to find a valid API key for authentication purposes.
• Solution: Ensure that you provide a valid api_key as an input parameter or set the GEMINI_API_KEY environment variable on your system.

Invalid input format

• Explanation: This error may arise if the input_text does not conform to the expected format or is too vague.
• Solution: Review your input_text to ensure it is clear, concise, and provides enough detail for the expansion process.
